Error on SyncroSim Run because of .Net version

[leonardo-frid]

I recently encountered this error when running a model on a windows server 2012 AWS instance:
[Failure] An item with the same key has already been added.

The same library ran fine on my local laptop. After some searching I found that the most recent .Net version on my laptop was 4.6.1 and that this version was not on the AWS instance. I installed this version of the .Net framework on the AWS instance and that solved the problem.

Has this issue popped up any more? I just received this error when trying to run a ssim.

Hi Kevin,
I have not experienced this error recently. However, I did update the AWS instance to a more recent 2019 Microsoft Windows Server. What operating system and .Net Framework version are you running? Are you able to run the model on a local machine but not on your server?

To check what versions of .Net you have installed you can run the following line of code in Windows Powershell ISE:
Get-ChildItem ‘HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP’ -Recurse | Get-ItemProperty -Name version -EA 0 | Where { $_.PSChildName -Match ‘^(?!S)\p{L}’} | Select PSChildName, version

You should then get some output that looks like this:
PSChildName Version
